On vertical these slopers will yield a V1/V2 feel, so you can imagine that on a 45 degree wall you are going to be in the V8/V9 realm. That's all assuming good feet and set as a ladder. It's very easy to set V10 plus with these in steep terrain. What's nice about these slopers is that when you try to pinch them, your thumb ends up having to go really wide and lands on yet another bad slopey surface.
